[Nuki Opener Issue]Door not open when bell is deactivated

Hey guys,
installation of my opener did working mostly fine :muscle:. Bit if i aktivate the ring suppression and Someone is ringing the bell, the bell will become a low powered signal (doesnt ring because the signal is to low) but opener dosnt open the door.

If i deactivate ring suppression, everything works. Ring bells and door will Open.

I can confirm this behavior. When option “ring suppression” is activated, ring to open doesn’t work and there’s no ring-tone anymore/ at all.
